What percentage of the transmitted signal is contained in the side lobe of the RADAR cone?

The correct answer indicates that 20% of the transmitted signal is contained in the side lobe of the RADAR cone. This is significant because the side lobes, while not the primary focus of radar transmission, can influence the accuracy and detection capability of radar systems.

In radar technology, the main lobe is the cone in which the majority of the signal's energy is transmitted; however, side lobes can still capture a considerable amount of energy, which can lead to false readings or interference due to objects or targets that are not directly in the primary beam. Understanding that 20% of the signal can be found in these side lobes highlights the importance of accounting for side lobe interference when interpreting radar data. This knowledge is crucial for effective speed detection and enhances the operator's ability to make accurate assessments based on the received signals.

Other choices suggest different percentages, but they do not capture the accepted understanding of radar signal distribution, which has been established in radar technology literature and training. This understanding underscores the importance of acknowledging the side lobes when analyzing radar performance and reliability in speed detection contexts.
